Recently grip strength has become a limiting factor for some exercises mainly RDL due to the (relatively) extended period of time under tension.
I am tempted to use straps, but also want to increase my grip strength.
What are your go to exercises for grip?
Lots of people enjoy grip work as its own field of training, or need it for a sport-specific purpose (such as climbing), and I'm sure some have success with supplemental grip training for other lifts.
But in my experience, grip strength is very specific to the activity, and if you're trying to increase grip strength for an activity that is already very grip intensive, then piling on more isolated grip training is more often than not ineffective at best and counterproductive at worst.
For instance, I do a lot of KB ballistics and clubbell swinging, where grip is often a limiting factor (on top of plenty of pullups and rows), and I would not recommend supplemental grip training for either. Not only is the activity itself the best and most specific grip training for those activities, but the fresher my grip is, the more of it I can do. To me, the best way to increase my grip strength and endurance for snatches and mills is more snatches and mills.
If you were a powerlifter having trouble holding onto weights you know you're strong enough to pull, okay, maybe some rack holds would be in order.
But for RDLs I'd just use straps and not think twice about it, especially if you're already doing KB ballistics, regular DLs or other training that taxes (and develops) the grip.
There's no moral dimension to using straps -- although there may be political, religious and other ideological dimensions ;-).
